MAGNETIC RECORDING DEVICE HAVING GRAPHENE PROTECTION FILM AND MANUFACTURING METHOD OF THE SAME

摘要

To provide a magnetic recording device having a graphene protection film having a single atomic thickness and a manufacturing method of the same.SOLUTION: A magnetic recording device 1 includes a substrate 100, an intermediate layer 101 arranged on the substrate, a magnetic recording layer 106 arranged on the intermediate layer, and a graphene protection film 108 arranged on the magnetic recording layer. The graphene protection film 108 includes at least one layer of a graphene single-atom layer that is a sheet-shaped single-atom layer of a sp2-bonded carbon atom. A transition layer 107 is inserted between the graphene protection film 108 and the magnetic recording layer 106. The transition layer includes carbon and at least one metal of the magnetic recording layer.SELECTED DRAWING: Figure 1
